Hello, I was wondering if anyone could help to explain something simple to me, I am lost for answers, and this is something a 7th grader should know I am assuming. C2H2 + N2O ---> CO2 + N2 + H2O. Now this may seem like a retarded question, but how can there be two oxygen molecules in the completed reaction formula when there's one in the original? Is it because this reaction is somehow producing another oxygen atom? or is there some balancing problems that I have? I am a novice at chemistry, just started taking it, so some clearification would be really helpful. Thanks in advance.
